ENOGH HIDDEN, 0F NE\\' YORK, N. Y.

SHIP-S LIGHT.

Specification of Letters Patent No. 23,247, dated March 15, 1859.

T o all whom it may concern:

Be it known that I, ENocII HIDDEN, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Ship-Lights; and I do hereby declare that the following is a full` clear, and exact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

The nature of my invention consists in the construction of shi Jv lights whereby the frame containing the glass may be removed at pleasure, and in constructing the fastening of a button with inclined face having its bearing above the frame7 and provided with a swivel handle or lever capable of being brought into use when desired, and then susceptible of being removed out of the range of the light; the details of construction and operation of these improvements will be understood from the following description and reference to the drawing.

Figure 1,- a a is the plate frame of the light, with its rim to which is attached the frame b ZJ, containing the glass light c c. The frame a a has the usual recess with india rubber embedded therein, against which the frame b Z) is pressed and thereby made air and water tight by means of the inclined-plano segmental button c operated by the handle or wrench j', attached to the joint pin g so as to be turned out of the way when not in operation. The inclined surfaces of the buttons act against the inclined sides of the slots 71. 71. in lugs of frame a c, as seen in Fig. 2, and produces the pressure necessary to insure the requisite tightness. The wrenches f f are attached to the pins g by the ,pins z' z' as seen in Figs. 4l and 5, where these parts are shown full size.

Fig. l shows the light in its place with vone of the buttons just entering its slot., and

the other secured in its position and the lever f so raised as not to obstruct the light (as seen in Fig. 2). In this view there are also shown the recessed parts of the ring of the main frame where the lugs are, admitting of a larger bearing for the buttons.

Fig. 2 shows the construction of the hinge of the glass frame, there being a stationary pin (l across the open jaw, formed by the rim of the main frame, over which a hook on the frame o passes and forms a hinge. rlhis construction admits of the removal of frame Z) when the glass is accidentally brokenand the immediate substitution of a spare frame. This figure also shows the slots 7i. in the lugs of main frame against the inclined edge of which the buttons operate, and also shows a button c with its wrench raised. The loop or suspension piece Z for retaining the light frame in its proper position is put in to suit circumstances.

Figs. 3, at and 5 show the buttons in detail with wrench.

Fig. 6 shows pin g secured in a portion of main frame.

Fig. 7 shows a portion of the same frame with position of pins g g.

Figs. 8 and 9 show the loop and suspension piece.

A modification of the fastening is shown in Figs. 10, 11, 12, and 13, where an inclined surface of a flange lon a spindle presses upon the light frame Z) Z), said spindle being drawn downward by a screw passing downward into the main frame a a.

Fig. 10 shows a portion of main frame a, showing the screw spindle with the flange m which is inclined on its under surface.

Fig. 11 is an edge view of the fastening and Fig. 12 is a front view.

Figs. 13 and 14 show the spindle and flange full size. The spindle bears against the upper portion of lug o, and when turned by wrench f is screwed int-o the main frame and by the pressure of the inclined surface of the flange m which constitutes the button, the lightv frame is forced upon the main frame as before stated. A screw pin -n is inserted in the spindle to limit its movement when adjusted.

The wrench f on the end of the spindle can be turned out of the way in the same manner as those before described.

That I claim and desire to secure by Letters Patent, is

1. The swivel wrench f of the button and supporting the shaft or spindle thereof by the brace piece 0 above the frame, substantially as, and for the purpose set forth.

2. The inclined surfaced button as described with swivel wrench in combination with the slotted lug of the main frame as signed my name before two subscribing Witset foIrth. b t. t1 t1 f l nesses.

3. n com 1`na lon W1 '1 1e a oresalc con- T struction, the attachment of the light frame E' HIDDEL" 5 b to the main frame a, by means of the hook /Vtnesses:

and pin as before described. JAS. D. CLARY,

In testimony whereof I have hereunto ALEX. MCDONALD SPRAGUE.
